Write a Java test

Write a simple test scenario, compile it, and execute it.

1. Begin by running the Genero Ghost Client ggcgen tool to create a skeleton application.

   ggcgen java --skeleton myapp_tests

   The myapp_tests_provider.java file is created in the "scenario" package:

   /*
    * Generated using Genero Ghost Client 2.00.06-201905141203
    */
   package scenario;
   
   import com.fourjs.ggc.ScenarioProvider;
   import com.fourjs.ggc.Scenario;
   import com.fourjs.ggc.Client;
   import com.fourjs.ggc.generator.ScenarioChecks;
   import java.util.concurrent.ConcurrentLinkedDeque;
   
   public class myapp_test2_provider implements ScenarioProvider
   {
     private final ConcurrentLinkedDeque<Scenario> scenarios;
   
     /* Instance initializer */
     public myapp_test2_provider()
     {
       scenarios = new ConcurrentLinkedDeque<>();
   
       /* Register scenario functions */
       scenarios.add(new scenario_0());
   
     }
   
     /* Scenario myapp_test2 id: 0 */
     private class scenario_0 implements Scenario
     {
       @Override
       public void play(Client client)
       {
         
       }
     }
   
     @Override
     public Scenario nextScenario()
     {
       return scenarios.removeFirst();
     }
   }

   In this scenario:

   1. The code begins by importing the Genero Ghost Client Java classes.
   2. The myapp_test2_provider() method implements the com.fourjs.ggc.ScenarioProvider interface.
   3. A function (scenario_0) with the id of 0 is registered in the scenarios variable. A test may register multiple test scenarios in this variable. They run in the sequence registered.
   4. A scenario_0 class is declared. This implements the com.fourjs.ggc.Scenario interface, which requires the method play to run the test.
2. To the play method of the scenario_0 class add code to test an application.
   For the test, the window name is retrieved from the client and the action cancel is triggered.
